My first budget 1675 built

[Fraist]

Hello everybody. I am reading for some time the forum and i decide to try to make my 1675 GMT Pepsi. Period 1971/79
I have read as much as possible threads for this built and i have decided to go with a low budget built because is my first built and i will definitely mess things up .

For the moment i am sourcing the parts for the built.

1. Case
I already purchase a Milk case, insert and bezel.

2. Caliper
I was thinking to go with the HZ6460 or to buy a 2836-2 and to add a GMT gear. I don't know what is the best option. Do you have something to propose? I buy directly from eBay or i can buy a better movement from somewhere else?

3. Dial + crystal
This parts confuse me. I have read that i need a clark 25-116 crystal but i don't know if i buy a eta dial the date will be shown correct in the cyclops. Or i have to buy a dial for 1575 cal and glue new feet to have correct date position in the cyclops? Dial i was thinking Yuki or Rafflesdials. Any other proposals?

4. DW
again i believe this has to do with the dial position eta or gen spec. Any place to buy?

5. Crown and tube
I have read that i need a 5,3 mm. ( twinlock 24-530-0 )

I contact this seller in ebay to buy one and he insists that i need the 6,3 mm.
https://www.ebay.de/itm/Corona-Crow...-/294224666259?_trksid=p2349624.m46890.l49286
Do you have a recommendation for reasonable price crown purchase (not original) that will fit my case?

4 Hands
What are the options for eta? Ebay from Raffles or is better to buy from somewhere else for better quality but not Gen.

5. Bracelet
I want to go with jubilee. First option is the 6251 but i am not able to find one for cheap. Or i don't know where to search Second option is the 62510H
Do you have a recommendation where i can find one of the above reasonable priced?

Sounds great. Starting with a Milk case this will already be beyond a ‘budget build’!

get the HZ6460 as I’m not sure you can buy the GMT module separately. It is a 2836-2, but with the GMT module bolted on.

yes 25-116.

go for the best dial you can afford. The Milk Case is gen spec (or very close) so you need a gen spec dial. I’d opt for a dial from Ruby (or similar provider), but there are others (more expensive and less). eBay has some ‘refinished’ gen spec dials.

DW (or date wheel overlays) are a bit problematic (in terms of finding one with good font and alignment). Read up on the forum to find out more;

https://forum.replica-watch.info/forum/vintage-watches/8465738-hunting-open-6-9-dwo


There are other DWO threads on here as well, but I can’t find them now...look through the vintage section.

Lots of Milk case stuff in this thread;
https://forum.replica-watch.info/forum/vintage-watches/8504111-project-rwi-raffle-win-a-1675-build

you need a 5.3mm crown.

Hands; lots of options. Have a read on here-some people use Tudor hands/ WSO Tudor hands/ raffles etc. spend the time reading up/ you won’t regret it.

markiemark is selling some very nice Jubilee bracelets by the look of it

*other jubilees are available

Thanks for the help.

I will ask a price from Rubi for dial.

I was also looking the Yuki dials that is also available for ETA movement.

I had in mind to use eta dial so not to have to glue new feet to the dial but I am not sure if the date window position in the eta version will cause problems with the cyclops or I will not be able to find a open 6 and 9 DW.

I just order the crown from the bay seller I mentioned before and i will wait to see what it will come.

I have already seen the jubilee from markiemark. I am looking first for the 6251

Are you looking for a gen or rep 6251?

 

[Fraist]

rep 6251

 

[markiemark]

rep 6251

I think I have never seen a rep 6251, but not 100% I do know there are Vietnam rivet ones...

A small update.

case received and for my eyes the quality is there. Excellent construction and finish.



The negative is that the bezel is a little smaller that the insert so I have to sand down the insert.
I am waiting for a calliper to see how much sand is needed or if I can increase the bezel size.


I receive the crown and tube. The quality if fine for me.

The only issue is that the tube does not have O-ring in the side that screws to the case. Does anyone knows what ring I have to use (if necessary).
I have also seen some people that glue the tube with loctite. I am also thinking to do something like that but I am afraid that I will may damage the case if I decide to remove the glued tube.



I am still looking for cal.

• one idea is the Asia 2836-2 GMT second
• alternative is the DG3804 GMT much cheaper and low bit

for the 2836 I can find hands. Does anybody knows if I can find good quality hands for the DG3804?

Very nice! I advice you work on the bezel recess for the insert instead of trimming the outer diameter of the insert. This way, if you decide to go gen insert, you will have the bezel ready. Gen inserts are 37.75mm, if you can get the bezel recess to 37.68~ it will snug the insert nicely. However, check the od of your insert and the id if the bezel recess and see where you are at so you can have better judgement. Usually you do bit by bit, dont rush or you will mess something for sure. As for hands, check tiger concepts, i think they have the closest to gen gmt hand at least, im swapping my raffles gmt hand to tiger concept gmt hand, (big arrow) currently in the mail. I beleive a2836 and dg3804 have same hole sizes. As for the crown, you could have bought a used gen which can usually be found for 75-100 on the bay. For a date wheel overlay, check with yodog, he might have some of his own for sale.. they are the best dwo ive seen. My 1675 from him has it. 3804s are finicky when it comes to keyless stuff, id advice the a2836 which is the hz6460 per se. Already with the gmt stuff added.

o-ring 29-05300 for 24-5320 tube
o-ring 29-0530 for 24-530 crown
If I were you I would change all gaskets and o-rings ...
You can find complete sets (including caseback gasket 29-325-10 for $15 to $20 shipped

And please do NOT glue the tube ... if your tube has slots so that you can use an Horotec tool for screw-in tubes that'll be enough.
Grease the 29-05300 o-ring and do not screw too much or you'll make it useless.
Of course you can put some BLUE Loctite 243 on the tube threads before you screw it.
Loctite 243 is not exactly a glue but a medium strength thread-locker (what we call "frein-filet" here in France) ... it will just prevent the tube to unscrew due to vibrations

Thanks for the help and the measurements. I will measure my and I will try to open it if possible.
I didn't knew tiger concept. I will probably make a trial order to see.
If I am not able to water tight the case I will buy Gen crown / tube you have right.

Thanks for your help. with the codes that you sent me I fount the part that I need. Is the 29-05310 metallic sealing washer. Unfortunately my tube does not have slots. I will probably buy one with slots for better installation.

Yuki's states his ETA 1675 dial diameter as 27mm however 27.30 is needed to allow the dial not to pass completely though. I measured Milk's 1675 opening and is gen spec. If Yuki's dials are indeed a true 27mm they will be to small and pass the resting ridge which is a shame given he sells ETA feet position dials.

 

[Fraist]

A small update.

I had already purchased the Yuki dial for 1675 movement with feet at 30 and 57 min in order to fit in Milk gen spec case.

I received yesterday the dial and I am a little bit confused. The dial is exactly 27,00 mm and Milk case rehaut is also exactly 27,00 mm.




The lip in the down side of the rehaut that blocks the dial to pass through is 27,55 mm so as bcapa40 mentioned probably I need a bigger dial for not pass the rehaut.




In my case the dial is just passing through and I am confused. Is that normal? any ideas how to fix that?

I have already purchased a Sternkreuz XS 302.450 crystal. Was the only available period that I ordered.

The fitment to the case was able to be done with my hand with a bit of pressure. After the crystal fit the outside diameter of the crystal was 30.25 mm

The Milk retaining ring was able to slide with hand pressure to the crystal (crystal not installed to the case), and the internal diameter of the crystal was stretched to 29.70 mm

The Milk case diameter for the crystal is 29.90 mm

The question is the 0.20 mm difference will let the retaining ring/crystal/case sit together or the difference is too big ???

I checked for gen crystal measurements but I didn't find anything.

What I found was the second type of 116 crystal from Sternkreuz the XS 300.158.

This crystal has a little smaller O.D. (30,00 instead of 30.20) and the same ID so I believe this will be able to fit easier. Or maybe is worse for water tightening ...

The other differences are the height of the crystal 3.9 vs 3.7 mm and the most serious is the position of the cyclops.

One position the cyclops 98 mm from the center and the second to 87 mm from the center. In both cases, the date weel window is not centered at all.

The best position of the cyclops to be spot on is 93 mm from the center

I checked other crystals like Clarks that a lot of builts use it. I was not able to find dimensions but I found a picture. This crystal seems to be similar to XS 300.158

Do you know what is the correct part?

The Rolex crystal sits also a little bit off-center or is spot on?

Do you have center measurements of the Gen 116 crystal to compare?
